Abstract

Papaya and carrot are rich in natural pigments, especially b-carotene. Unfortunately, in most cases, natural pigments are less stable than the synthetic ones when they are put in a variety of treatment conditions, such as pH. In this work, the stability of the papaya and carrot extracts were evaluated in various pH, which ranges of 1-10 for 7 days. The extracts were obtained by a slow juicer, followed by encapsulation and drying by a freeze dryer. The extracts were then dispersed in buffer solutions and the chroma and color difference (DE) values were calculated from the obtained lightness (L*), redness (a*), and yellowness (b*). The results showed that carrot extract was better than the papaya extract in terms of chroma values. It was also shown that both extracts were not stable under acidic condition, but more stable in neutral to alkaline condition. The acid condition facilitated the cleavage of the conjugated bonds in the b-carotene, which in turn caused the color degradation in the papaya and carrot extracts.

Abstract

Carotenoids are pigments of red, yellow and orange which are found in plants, animals and bacteria, and are known to have antioxidant activity. This study aims to identify the carotenoid pigments detected in seagrass Syringodium isoetifolium bacterial symbionts. Isolation of bacteria was conducted using dispersive media Zobell 2116E. Bacterial isolates were cultured and then centrifuged at 8000 rpm for 10 minutes and extracted using methanol. Identification of the pigment was done by using High Performance Liquid Chromatography (HPLC) reversed phase ODS / C18. The mobile phase was carried out using a mixture of methanol: acetonitrile (7: 3 v / v). Free radical reduction activities determined by the method of DPPH (diphenylpicrylhydrazil) and its absorbance was measured at a wavelength of 517 nm. Identification of the bacterial symbionts from the seagrass S. isoetifolium performed using 16S rDNA PCR method. The results showed that, of the 12 bacterial isolates obtained, isolate 7A was proven to contain caratenoid pigment. Pigment extracts of the bacterial isolates had free radical DPPH reduction activity of 40.4%. The results showed that the identification of bacteria isolates 7A had 100% level of kinship with the bacteria Bacillus amyloliquifaciens.

Abstract

The aim of this study is to investigate the expression of heat shock protein 70 (HSP70) on grouper infected by Nervous Necrosis Viral (NNV) with involvement of pigment-protein fraction (PPF) from Nannocloropsis oculata (N.oculata). Fish treatments were divided into three group, which are control, fish with PPF from N.oculata, and fish with PPF and NNV. After treatment for 23 d, fish were sacrificed, and their brain was harvested for protein analysis using SDS-Page. Fish blood was collected to examine the expression of HSP70 by hemagglutination and western blot analysis. The results showed that the expression of HSP70 was observed after treatment with PPF in NNV infected brain tissue and blood cell proved by SDS-Page and Western blot analysis.  Thus, PPF is responsible for the expression of HSP70 in infected tissues, indicating that PPF appears to have a function as an inhibitor of proliferation of NNV.

Abstract

The very small size of Synechococcus spp. as one important contributor of ocean primary productivity can be identified using its phycoerythrin pigment chromophores, phycourobilin (PUB) and phycoerythrobilin (PEB). Seasonal variation of the excitation (EX) ratio of PUB and PEB in the surface water of East Sea/Japan Sea was observed. This study aimed to describe the effects of environmental factors during different season to the excitation ratio of PUB and PEB contained Synechococcus spp.  Summer and winter showed slightly similar distributional pattern with PUBEX:PEBEX ratio > 1, while PUBEX:PEBEX ratio < 1 could be found in autumn and spring. The results of this study showed seasonal patterns of phycoerythrin pigment from Synechococcus were highly related with variability of environmental factors. High light intensity during summer and high salinity during winter were the reasons of high PUB:PEB ratio of Synechococcus spp. Moreover, high PUB type of Synechococcus spp. was also dominated the offshore study areas as the result of higher water clarity compared to the one in the coastal areas.

Abstract

Non-destructive measurement of plant chlorophyll concentration using the normalized difference vegetation index (NDVI) has long been standard practice to determine the plant health status. This is, because the NDVI value is correlated with the chlorophyll concentration which in turn is highly correlated with other vital plant parameters such as nitrogen and magnesium concentration. Initially the NDVI values were obtained from satellite imagery and thus could only be used to assess the health status of bigger ecosystems like forests and crop fields. With the introduction of handheld chlorophyll meters like the Chlorophyll Meter SPAD-502 Plus made by Konica Minolta, the same principle could be used to determine the chlorophyll concentration of single leaves. However, these devices still have one major shortcoming: They can only measure the chlorophyll concentration on one single spot on the leaf at a time. But depending on the species the chlorophyll concentration tends to vary significantly over the leaf. To overcome this shortcoming, we developed our PlantAnalyzer which offers better spatial resolution of the NDVI values and hence the chlorophyll concentration. Its technical realization and precision shall be elaborated in the following article.

Abstract

In the present work, a comprehensive statistical analysis was performed to evaluate the potential application of peel of local fruits from Malang, i.e. mangosteen, honey pineapple and red dragon fruits for natural yellow coloring agents. The yellow pigments from those fruit peels were extracted through a simple maceration method using distilled water, acetone and ethanol as the solvents. The CIE color space of the extracts was measured to obtain L*, a* and b* values. The obtained data were further analyzed using Principal Component Analysis (PCA), Multivariate Analysis of Variance (MANOVA) and Duncan Test to determine the most potent natural yellow coloring agent. All the extracts were appeared as mild to strong yellow liquid except for acetone extract for the peel of red dragon fruit extracts. From the CIE color space and PCA analysis, either ethanolic or acetone extracts of mangosteen appears as a strong yellow liquid and they are statistically not different. Interestingly, the MANOVA and Duncan test results are able to distinguish that the ethanolic extract of mangosteens? peel as the best candidate for natural yellow coloring agents because of its lowest L* and also highest b* variable values.

Abstract

Sweet potatoes, especially the orange and yellow-fleshed, are functional local food because they contain carotenoids which serve as a pro-vitamin A. The processing of sweet potatoes into noodles, fermented cassava or ?tape? and artificial rice is usually prepared through steaming. However, carotenoid is susceptible to degrade when it is subjected to high temperature, such as steaming. The objective of this research is to determine the effects of steaming on the color and carotenoid absorption spectra of local and excellent sweet potatoes which are correlated to the carotenoid content and to evaluate the difference of carotenoid spectral properties among sweet potatoes by principal component analysis (PCA). The steaming treatment decreased color values, such as lightness, redness, and yellowness. In addition, this process also influenced the spectral properties of carotenoid extracts of sweet potatoes. Steaming decreased absorbance and resulted in hypsochromic and bathochromic shifts. Madu Mojokerto, Manohara, local purple fleshed, Beta 1, and Papua Solossa sweet potatoes experienced some decreases in absorbance and a hypsochromic shift of ± 77 % and ± 2 nm, ± 40 % and ± 21 nm, ± 63 % and ± 28 nm, ± 44 % and ± 2 nm, and ± 20 % and ± 23 nm, respectively; while Antin 3 sweet potatoes experienced some decrease in absorbance of ± 36 % and a bathochromic shift of ± 28 nm. The PCA results showed that there were four groups of sweet potatoes based on spectrum shape and absorbance value.
